Background: AITP is a student organization of MSU. AITP uses a MySQL database to manage its membership. A student becomes a member by registering to AITP. The database records the member and registration information in the Member table of the database. A student does not have to pay the membership fee right at registration, but the membership will be activated only when the membership fee payment is received. The membership is valid for one year and can be renewed any time. The table member_fee_payment records all member fee payments including new and renew. AITP has polo shirt for members to order. Even though members typical orders one shirt for self but they can order as many shirts as they want. The table polo_order records the shirt orders. Associated with polo shirt orders, the polo_pay and polo_delivery tables record the shirt order payment and delivery information. Orders not paid will have NO payment information recorded.
